Replacement Drive Shaft Sensor - Dual Channel

The Replacement Drive Shaft Sensor – Dual Channel by AutoMeter (SKU ATM5212) is a precision magnetic pickup sensor engineered for high-performance tachometer systems that require accurate real-time engine speed monitoring. This dual-channel design allows simultaneous signal capture from multiple driveshaft or engine reference points, making it essential for street machines, race cars, and performance builds where reliable RPM data directly impacts tuning, shift timing, and overall vehicle diagnostics. Whether you're running a standalone engine management system or upgrading an existing gauge cluster, this replacement sensor restores accurate playback functionality to AutoMeter dual-channel tachometers.

Designed as a direct replacement component, the drive shaft sensor uses proven magnetic induction technology to detect driveshaft or reluctor ring rotation and transmit clean digital pulses to compatible AutoMeter instrumentation. The dual-channel architecture enables simultaneous monitoring of primary and secondary engine parameters, reducing signal noise and improving accuracy in complex ignition or fuel injection scenarios. Its compact form factor (5.7 × 1 × 7.75 inches) and lightweight construction (0.11 lbs) allow discreet installation near the driveshaft, differential, or custom-mounted reluctor wheels without adding bulk or parasitic load to rotating components.

Professionals and enthusiasts rebuilding or servicing AutoMeter tachometer systems benefit most from this OEM-equivalent replacement. Installation requires secure mounting in close proximity to a ferrous reluctor ring or factory driveshaft reluctance ring, with signal wires routed to the matching dual-channel gauge input. Verify compatibility with your specific AutoMeter tachometer model (reference the MPN 5212) before ordering. This sensor is ideal for carburetor and fuel-injection engines alike and works across naturally aspirated and forced-induction platforms.
